Programmed cell death (PCD) plays a crucial role in maintaining tissue homeostasis, with its primary forms including apoptosis, pyroptosis, and necroptosis. The caspase family is central to these processes, and its complex functions across different cell death pathways and other non-cell death roles have been closely linked to the pathogenesis of autoimmune diseases. This article provides a comprehensive review of the role of the caspase family in autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), type 1 diabetes (T1D), and multiple sclerosis (MS).

Oxygen scavenging systems (OSSs) are critical for dye stability in single-molecule fluorescence (SMF) experiments. However, the commonly used protocatechuic acid (PCA)/protocatechuate-3,4-dioxygenase (PCD) OSS alters DNA mechanical properties, limiting its applicability. To address this limitation, we examine the bilirubin oxidase (BOD) OSS, which had not been previously used in single-molecule experiments, alongside the pyranose oxidase and catalase (POC) OSS.

The flocculus, a small and distinct region of the cerebellum, plays a crucial role in coordinating eye movements, especially in stabilizing visual images on the retina during head movements. Damage or lesions in the flocculus can lead to a specific neurological syndrome called floccular syndrome. This syndrome is characterized by abnormalities in the vestibulo-ocular reflex (VOR), which helps coordinate eye movements with head movements to maintain clear vision.

This proof-of-concept study explores quantitative imaging of articular cartilage using photon-counting detector computed tomography (PCD-CT) with a dual-contrast agent approach, comparing it to clinical dual-energy CT (DECT). The diffusion of cationic iodinated CA4 + and non-ionic gadolinium-based gadoteridol contrast agents into ex vivo bovine medial tibial plateau cartilage was tracked over 72 h. Continuous maps of the contrast agents' diffusion were created, and correlations with biomechanical indentation parameters (equilibrium and instantaneous moduli, and relaxation time constants) were examined at 28 specific locations.
